1. WHAT [Dorzolamide/Timolol] IS AND WHAT IT IS USED FOR
[Dorzolamide/Timolol] is a combination of two medicines: dorzolamide and timolol.
• Dorzolamide belongs to a group of medicines called “carbonic anhydrase inhibitors”.
• Timolol belongs to a group of medicines called “beta-blockers”.
[Dorzolamide/Timolol] is prescribed to lower raised pressure within the eye in the treatment of glaucoma when beta-blocker eye drops used alone are not adequate.
2. BEFORE YOU USE [Dorzolamide/Timolol]
Do not use [Dorzolamide/Timolol]
■ if you are allergic (hypersensitive) to [Dorzolamide/Timolol], beta-blockers or any of the ingredients.
■ if you have now or have had in past respiratory problems such as asthma, severe chronic obstructive
bronchitis (severe lung disease which may cause wheeziness, difficulty in breathing and/or longstanding cough),
■ if you have severe kidney problems, or a prior history of kidney stones,
■ if you have a disturbance in the pH (acid/alkali balance) of your blood,
■ if you have certain heart problems, including certain heart rhythm disturbances producing an abnormally slow heart rate or severe heart failure.
If you think any of these apply to you, do not use [Dorzolamide/Timolol] until you have consulted your doctor.

You should also tell your doctor if you now have, or have had in the past, breathing problems, asthma or chronic obstructive pulmonary disease, Prinzmetal’s angina (chest pains while resting), other heart problems
2
(including disturbances of heart rate such as slow heart beat or severe heart failure), coronary heart disease (symptoms can include chest pain or tightness, breathlessness or choking), poor blood circulation disease (such as Raynaud’s disease or Raynaud’s syndrome), low blood pressure, diabetes as timolol may mask signs and symptoms of low blood sugar, overactivity of the thyroid gland as timolol may mask signs and symptoms and about any allergies to a medicine you have taken.
If you develop conjunctivitis (redness and irritation of the eye[s]), swelling of the eye or eyelids, skin rash, or itching in and around the eye contact your doctor immediately. Such symptoms may be due to an allergic reaction or may be a side-effect of [Dorzolamide/Timolol] (See ‘Possible Side Effects’).
Tell your doctor if you develop an eye infection, receive an eye injury, have eye surgery, develop other reactions or worsening of symptoms.
If you wear soft contact lenses, it is important that your lenses are removed before using your eye drops and not put back into your eyes until 15 minutes after using your eye drops as the preservative benzalkonium chloride may possibly discolour the contact lenses.
Before you have an operation and anaesthesia (even at the dentist), tell your doctor or dentist that you are taking [Dorzolamide/Timolol], as there may be a sudden fall in blood-pressure associated with the anaesthetic.

3. HOW TO USE [Dorzolamide/Timolol]
Always use [Dorzolamide/Timolol] exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.
The appropriate dosage and duration of treatment will be established by your doctor.
The usual dose is one drop in the affected eye(s) two times a day, for example in the morning and in the evening.
If you use [Dorzolamide/Timolol] with another eye drop, leave at least 10 minutes between putting in [Dorzolamide/Timolol] and the other medicine.
Do not change the dosage of the drug without consulting your doctor. If you must stop treatment, contact your doctor immediately.
Do not allow the tip of the container to touch your eye or areas around your eye. It may become contaminated with bacteria that can cause eye infections leading to serious damage of the eye, even loss of vision. To avoid possible contamination of the container, keep the tip of the container away from contact with any surface.
In order to secure correct dosage - the dropper tip should not be enlarged.
Instructions for use:
It is recommended that you wash your hands before putting in your eye drops.
It may be easier to apply your eye drops in front of a mirror.
1. Before using the medication for the first time, be sure that the tamper-proof seal on the bottle neck is unbroken. A gap between the bottle and the cap is normal for an unopened bottle.
2. Take off the cap of the bottle.
3. Tilt your head back and gently pull your lower eyelid down to form a small pocket between your eyelid and your eye.
4. Invert the bottle, and squeeze it until a single drop is dispensed into the eye as directed by your doctor. DO NOT TOUCH YOUR EYE OR EYELID WITH THE DROPPER TIP.
5. Repeat steps 3 & 4 with the other eye if instructed to do so by your doctor.
6. Put the cap back on and close the bottle straight after you have used it.
After using [Dorzolamide/Timolol], press a finger into the comer of your eye, by the nose for 2 minutes. This helps to stop dorzolamide/timolol getting into the rest of the body.
If you use more [Dorzolamide/Timolol] than you should
It is important to keep to the dose your doctor has prescribed. If you put too many drops in your eye or swallow any of the contents of the bottle, you may feel unwell, for example you may become light-headed, have difficulty breathing, or feel that your heart rate has slowed. If you feel any of the above effects you should seek medical attention immediately.
If you forget to use [Dorzolamide/Timolol]
It is important to use [Dorzolamide/Timolol] as prescribed by your doctor.
If you miss a dose, apply it as soon as possible. However, if it is almost time for the next dose, skip the missed dose and go back to your regular dosing schedule.
